What are spring loaded contacts?

Spring loaded contacts consist of a plunger (or head), barrel (or body), and a fully encapsulated fine spring, to provide the spring force required to maintain positive contact. All have a high durability, exceeding 10,000 mating cycles.

Spring Probes:

  • ATE Spring Probes in a variety of lengths and travel to cater for multi-height probing of printed circuit boards
  • Selection of head styles, suitable for a range of contamination levels
  • Choice of two-piece probes - sleeve stays fixed to the test equipment, but probe can be removed and replaced in the case of damage, wear or end-of-life

Spring Loaded SMT Contacts - Pogo Pins

  • Surface mountable vertical spring loaded contact pins, free height from 2.8mm to 8.2mm
  • Option of Through-hole peg - can be used for Plated-Through-Hole soldering, or just as a SMT location peg
  • Rounded contact heads with Gold finish for minimal wear
  • Some options supplied in Tape and Reel packaging for automated assembly systems

SMT Contact Pads

  • Multi-purpose flat contact pads for Surface Mount fixing - thicknesses between 0.1mm and 0.5mm
  • Supplied in Tape and Reel packaging for automated assembly systems
  • Gold finish for maximum wear resistance
  • Choice of contact pad shapes - square, round or oval
